Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at any   time   (even   with   the   ignition   off).
Engine oil level
The check is carried out either when the   ignition   is   switched   on   using   the  
o

il   level   indicator   in   the   instrument  
p

anel   for   vehicles   so   equipped,   or  
u

sing   the   dipstick.Checking using the dipstick

CITROËN
 
r

ecommends
 
that
 
you
 
check
 
the
 
level,
 
and
 
top-
up
 
if
 
necessary,
 
every
 
3
 
000
 
miles
 
(5
 
000
 
kms).
Check
 
all
 
of
 
these
 
levels
 
regularly,
 
in
 
line
 
with
 
the
 
manufacturer's   service   schedule.   Top   them   up   if   necessary,   unless   other wise   indicated.
If
 
a
 
level
 
drops
 
significantly,
 
have
 
the
 
corresponding   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop.
To
 
ensure
 
that
 
the
 
reading
 
is
 
correct,
 
y

our
 
vehicle
 
must

Checks
12 V battery
The battery does not require any maintenance.
However,
  check   that   the   terminals  
a

re   clean   and   correctly   tightened,  
p

articularly   in   summer   and   winter.Refer
  to   the   manufacturer's  s
ervice   schedule   for   details   of   the  
r

eplacement   intervals   for   these  
c

omponents.
Air filter and passenger compartment filter
Replace the oil filter each time the engine   oil   is   changed.
Refer
  to   the   manufacturer's  
s

ervice   schedule   for   details   of  
t

he   replacement   interval   for   this  
c

omponent.
Oil filterThe presence of this label, in particular
with   the   Stop   &   Start   system,   indicates   the u

se   of   a   specific   12   V   lead-acid   battery
 w

ith   special   technology   and   specification.
 T

he   involvement   of   a   CITROËN   dealer
 o

r   a   qualified   workshop   is   essential   when
 r

eplacing   or   disconnecting   the   battery.
Unless
  other wise   indicated,   check   these   components   in   accordance   with   the   manufacturer's   service   schedule   and   according   to   your   engine.
Other wise,   have   them   checked   by   a   CITROËN   dealer   or   a   qualified   workshop.
Depending on the environment (e.g. dusty a
tmosphere)   and   the   use   of   the   vehicle   (e.g. city d

riving),
 r
eplace them twice as often if necessar y .
A
  clogged   passenger   compartment   filter   may   have
 a

n   adverse   effect   on   the   per formance   of   the   air
 c

onditioning   system   and   generate   undesirable
 o

dours.
Particle filter (Diesel)
The start of saturation of the particle
filter   is   indicated   by   the   fixed  
i

llumination   of   this   warning   lamp  
a

ccompanied   by   a   warning   message.
As
 
soon   as   the   traffic   conditions   permit,  
r

egenerate   the   filter   by   driving   at   a  
s

peed   of   at   least   40   mph   (60   km/h)   until  
t

he
 
warning   lamp   goes   off.
If
 
the   warning   lamp   stays   on,   this  
i

ndicates   a   low   additive   level.
For
  more   information   on   Checking
levels
 

and   the   Diesel   additive   level   in  
p

articular,   refer   to   the   corresponding  
s

ection.
On a new vehicle, the first particle
filter
  regeneration   operations   may   be  
a

ccompanied   by   a   "burning"   smell,

Brake wear depends on the style of   driving,   particularly   in   the   case o

f   vehicles   used   in   town,   over   short
 d

istances.   It   may   be   necessary   to   have
 t

he   condition   of   the   brakes   checked,
 e

ven   between   vehicle   services.
Brake pads
For information on checking brake disc   wear,   contact   a   CITROËN   dealer  
o

r   a   qualified   workshop.
Brake disc wear

In
  order   to   optimise   the   operation   of  
u

nits   as   important   as   those   in   the  
b

raking   system,   CITROËN   selects   and  
o

ffers   very   specific   products.
After
  washing   the   vehicle,   dampness,  
o

r   in   wintry   conditions,   ice   can   form  
o

n   the   brake   discs   and   pads:   braking  
e

AdBlue® additive and SCR system
f
or
 
BlueHDi   Diesel   engines
To assure respect for the environment and c
onformity   with   the   new   Euro   6   emissions  
s

tandard,   without   adversely   affecting   the  
p

er formance   or   fuel   consumption   of   Diesel  
e

ngines,   CITROËN   has   taken   the   decision   to  
e

quip   its   vehicles   with   an   effective   system   that  
a

ssociates   SCR   (Selective   Catalytic   Reduction)  
w

ith   a   particle   filter   (FAP)   for   the   treatment   of  
e

xhaust   gases.
Presentation of the SCR system
Using a fluid called AdBlue® containing urea, a c
atalytic
 
converter
 
turns
 
up
 
to   85%   of   nitrogen  
o

xides
 
(NOx)
 
into
 
nitrogen
 
and   water,   which   are  
h

armless
 
to
 
health
 
and
 
the
 
environment. The
  AdBlue
® additive is held in a special t
ank
 
located
  under   the   boot   at   the   rear   of  
t

he
 
vehicle.
 
It   has   a   capacity   of   17   litres:   this  
p

rovides
 
a
 
driving   range   of   about   12   500   miles  
(

20
 
000
 
km),
  after   which   an   alert   is   triggered  
w

arning
 
you
 
when   the   reserve   remaining   is  
e

nough
 
for
 
just   1   500   miles   (2   400   km).
During
 
each
  scheduled   service   of   your   vehicle  
b

y
 
a
 
CITROËN   dealer   or   a   qualified   workshop,  
t

he
 
AdBlue
® additive tank is refilled in order to a
llow
 
normal   operation   of   the   SCR   system.
If
 
the
 
estimated   mileage   between   two   services  
i

s
 
greater
 
than   12   500   miles   (20   000   km),   we  
r

ecommend
  that   you   go   to   a   CITROËN   dealer  
o

r
 
a
 
qualified   workshop   to   have   the   necessary  
t

op-up
 
carried   out. Once
  the   AdBlue
® tank is empty, a s
ystem
 
required
  by   regulations  
p

revents
 
starting
 
of   the   engine.
If the SCR

is faulty, the level of
emissions
 
from
 
your   vehicle   will   no  
l

onger
 
meet
 
the
 
Euro   6   standard:   you  
v

ehicle
 
becomes
 
polluting.
In
 
the
 
event
 
of
 
a
 
confirmed   fault  
w

ith
 
the
 
SCR
 
system,   you   must   go  
t

o
 
a
 
CITROËN
 
dealer   or   a   qualified  
w

orkshop
 
as
 
soon   as   possible:   after  
a

 
running
 
distance   of   650   miles  
(

1 100
 
km),
 
a
 
system   will   be   triggered  
a

utomatically
 
to
 
prevent   engine   starting.
